27 is what percent of 1691 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 1691 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 1691, so we can write it down as 100%=1691.
4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.
5. Now we have two simple equations:
1) 100%=1691
2) x%=27
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=1691/27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27 is what percent of 1691

100%/x%=1691/27
(100/x)*x=(1691/27)*x       - we multiply both sides of the equation by x
100=62.62962962963*x       - we divide both sides of the equation by (62.62962962963) to get x
100/62.62962962963=x
1.5966883500887=x
x=1.5966883500887

now we have:
27 is 1.5966883500887% of 1691
